In situ calibration

Purpose – To examine the possibilities for dry calibration or in situ calibration for flowmeters in the field.Design/methodology/approach – Reviews history and current situation with regard to in situ/dry calibration of flowmeters. Its acceptability for modern flowmeters is considered. Various options are considered to achieve dry calibration or in situ calibration. The possibility of action at a distance via the internet, for example, naturally follows from these developments.Findings – The paper concludes that this development is likely to be of importance to manufacturers. It will need to be addressed by certification authorities.Originality/value – The concepts will reduce the cost of calibration and the discussion should be of value to research workers, industry and government.
